Cultivation in Ohio

Primary Uses:

Oil

 Planting:

Seed do not germinate well when soil temperatures are below 70 degrees Fahrenheit.  A good rule of thumb is not to plant until at least a month after the last killing frost in the spring. However, soil temperature is a better indicator of when to plant. For good germination plant after the soil temperature at the eight inch depth at 8:00 a.m. averages 68 degrees Fahrenheit for ten days.

 Seeding Rate:

The sesame seed is planted from 0.75 to 1.5 inches deep. A planting rate of 3 pounds per acre (25-35 seeds per foot) is recommended for sesame planted on a 40 inch row spacing.

Fertility:

Sesame will require approximately 40 to 80 pounds of nitrogen per acre on irrigated production and 25 to 60 pounds of nitrogen per acre on dryland production.  Apply phosphorus and potash according to soil test.

Insects:

Green peach aphid, (cotton aphid does not affect sesame), thrips, grasshoppers, cutworms, and white fly are the most common insects attacking sesame.

Diseases:

Bacterial leaf spot is most likely to cause trouble. Fusarium wilt can be a serious problem in South Texas on fields previously planted in sesame. The current sesame varieties have tolerance to Fusarium. Farmers have planted sesame on fields with serious cotton root rot problems and never seen the problem. However, there is a root rot (Phytophtora parasitica) that does attack sesame. Verticillium wilt also attacks sesame.

Harvest:

Sesame is ready for harvest when the stalk dries down where it will be cut. For best yields, sesame must be harvested as soon as the crop is ready. The present shatter resistance varieties of sesame will hold the seed through 6 weeks of rain.

Comments:

Some sesame varieties are grey or brown in color and a specialized sesame, black in color, is sold in Japan, Korea, China, Vietnam, Thailand, and Myanmar. The black seed coat color is important since the color can bleed into the seed and the dehulling process will not remove the color.    TCS
